I want to start an investigation on the Brain/Neocortex of Sara Bareilles

I want to start an investigation on the brain of Sara Bareilles. She is very busy with her brain as a song writer. I can only imagine. So, i'm curious as to the activity fluctuations of it. Now from her videos, I gather that she is for the most part humble and simple minded during the course of a regular day(moderate brain activity), but being writer of her caliber there must be some sort of switch during her process of writing...... to where the brain activity in her neocortex reaches levels that us mere mortals can only dream about achieving.
